Controlling Roon from the iOS Notification Center as a widget (Using Workflow App)

This is what my Workflow looks like:


In the first text box, you should enter the IP address of your Node server, followed by the port. For example, in my setup, my IP address is 10.0.1.38, and my port is 3000. So in the text box, I enter 10.0.1.38:3000.
Let me know if that works for you.
